This is my latest OpenSCAD PLA gear kit. The pin connectors are specially designed for PLA materials - they are flexible and not prone to cracking, even when inserted. The core concept of this kit is that the gear center and pins remain unchanged, and only the outer shell can be flexibly replaced. In this way, the gears can be interchangeable, greatly simplifying the process of building and creating various gear combination models. I wish you all a fun time!

Updated on August 31, 2013Some PLA colors have encountered the problem of loose pins during use? To address this, I've specially introduced two thickened pin base plates: one with a diameter increase of 0.2mm, and the other with a 0.4mm increase, effectively solving this problem.
